Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558826, here are decompositions:

3 + 31558823 = 31558826
7 + 31558819 = 31558826
37 + 31558789 = 31558826
67 + 31558759 = 31558826
97 + 31558729 = 31558826
109 + 31558717 = 31558826
163 + 31558663 = 31558826
193 + 31558633 = 31558826

Showing the first eight; more decompositions exist.
